Historically NFS has not been re-exportable. I know that since we started on Ganesha, the
NFS client has added functions so that name_to_handle_at and open_by_handle_at system
calls will work. I'm not sure there wouldn't be hidden issues with re-exporting
this way. You could try removing the restriction and see if it works, but don't be
surprised if there is some issue.

Subject: [NFS-Ganesha-Devel] Re-exporting mounted NFS file system using
Ganesha?
Hi. We'd like to use Ganesha for this purpose using the VFS FSAL. However, it
seems Ganesha can only do a Proxy re-export from another NFS server. This
does not work for our use case for security reasons. Looking at the code, I
found the following in FSAL/commonlib.c:
static void posix_create_file_system(struct mntent *mnt) {
struct fsal_filesystem *fs;
struct avltree_node *node;
if (strncasecmp(mnt->mnt_type, "nfs", 3) == 0) {
LogDebug(COMPONENT_FSAL,
"Ignoring %s because type %s",
mnt->mnt_dir,
mnt->mnt_type);
return;
}
Is there a reason why you don't allow NFS mounts to be re-exported using VFS
FSAL? Thanks.
-Jeff
